Description

low level cryptographic library (public-key cryptos)
Nettle is a cryptographic library that is designed to fit easily in more or
less any context: In crypto toolkits for object-oriented languages (C++,
Python, Pike, ...), in applications like LSH or GNUPG, or even in kernel
space.

It tries to solve a problem of providing a common set of cryptographic
algorithms for higher-level applications by implementing a
context-independent set of cryptographic algorithms. In that light, Nettle
doesn't do any memory allocation or I/O, it simply provides the
cryptographic algorithms for the application to use in any environment and
in any way it needs.

This package contains the asymmetric cryptographic algorithms, which,
require the GNU multiple precision arithmetic library (libgmp) for
their large integer computations.
